show diagram water tube boiler high pressure
See nominally, condensing gas show diagram water tube boiler high pressure premix was added called "premix" combustion technology, the fuel before entering the combustion chamber, with the gas in advance (i.e., air) sufficient mixing and precise adjustment mechanism according to, in order to achieve optimum combustion, improve the fuel efficiency corresponding to about 10% will; and can effectively reduce harmful substance emissions in flue gas emissions.
What are the benefits of using the bottom of the steam heating have? What are the precautions? Promote water circulation established in advance (L), to reduce the temperature difference between upper and lower walls of the drum: 1, in the early ignition prior to cold start or show diagram water tube boiler high pressure, steam-heated cast with the bottom has the following advantages. (2) shorten the start-up process, start the process of reducing fuel consumption. (3) water-cooled wall since the heating surface is heated to improve the furnace temperature, is conducive to early ignition combustion of oil. (4) easier to meet the requirements of the boiler steam drum wall temperature at the pressure test. 2, using the bottom of the steam heating the following should be noted: before administration with the bottom of steam heated, the first hydrophobic vapor source conduit exhausted, and then put into use. With little initial investment should be moved into the steam valve, to prevent excessive vibration, and then gradually turn up in accordance with heated and open enough. Put into use during the steam supply pressure should pay attention to the difference with the furnace drum pressure, especially after the boiler ignition boost should pay attention to the difference of not less than 0.5MPa, should be promptly splitting up if this value , water was poured into the pot to prevent the backup source steam main pipe.
The fuel regulation subsystem of hot water show diagram water tube boiler high pressure adopts a feed-forward-feedback cascade control system similar to the steam turbine power-frequency electro-hydraulic control system. The main regulator adopts the proportional regulator, which corresponds to the frequency difference amplifier in the steam turbine power-frequency electro-hydraulic regulating system. The proportional band is equivalent to the unequal rate of the steam turbine. The size of the proportional band represents the capacity of the hot water boiler with load, and the larger the proportional band, the greater the load capacity of the hot water boiler. The capacity of hot water boiler with load is stronger; The auxiliary regulator adopts the proportional integral regulator, which corresponds to the power regulator in the power-frequency electro-hydraulic regulation system of steam turbine, and introduces the feedback signal of fuel quantity to the power-frequency electro-hydraulic regulation system of steam turbine. The effect of the first stage pressure signal of steam turbine is to eliminate the spontaneous disturbance of the fuel quantity of hot water boiler quickly. Hot water boilers are mainly used for heating and bathing. The hot water boiler circulates the hot water of the heat preservation tank through the hot water circulation pump and heats the hot water of the water tank again and again so as to achieve the purpose of bathing. The hot water boiler circulates the hot water of the heating pipe through the hot water circulation pump, and meets the requirement of people's heating through the radiator (radiator), and the hot water boiler and the hot water circulation pump cooperate with the heat exchanger can realize the double function of bathing and heating. The inlet speed of hot water boiler before start-up should not be too fast, usually no less than 4 in winter H, 2 to 3 hours in other seasons, especially at the beginning of the inflow. The inlet water temperature of a hot water boiler is generally at 50 ℃ 90 ℃, so that the difference between the feed water temperature entering the drum and the wall temperature of the drum is less than 40 ℃. The inlet water temperature of the gas-fired hot water boiler without complete cooling can be compared with the drum wall temperature, otherwise, the inlet water speed should be slowed down. When the feed water enters the drum, it always contacts the lower half wall of the drum first. If the difference between the feed water temperature and the drum wall temperature is too large, the speed of entering the water is fast, the upper and lower walls of the drum, the inner and outer walls will produce a larger expansion difference, resulting in a greater additional stress to the drum. Causes the steam drum to deform, produces the crack when serious. Because the wall of the drum Thick, slow expansion, and connected to the drum wall thin wall, expansion faster. If the inlet temperature of gas-fired hot water boiler is too high or the inlet speed is too fast, it will cause uneven expansion, crack of welding joint and damage of gas-fired hot water boiler.
Zhengzhou Sunrise Optoelectronics Technology Co., Ltd. by the Dongxu Group, Henan Province, the state-owned asset management companies and Zhengzhou Investment Holdings Limited jointly made, mainly engaged in flat panel display and solar industry design materials, manufacturing and sales operations. Sunrise Optoelectronics project has been put into a production line, the second phase will continue the expansion, three new production lines to meet the production needs of Project Phase II, Sunrise Optoelectronics urgent need to increase new show diagram water tube boiler high pressure equipment. After investigation and screening of a number of boiler brands, determined to cooperate with the fast boiler, steam signed a 10-ton integrated condensing gas steam boiler (WNS10-1.25-Y.Q).
